Arby’s Nutrition Calculator: Calories, Protein, Carbs & Sodium
We Have The Meats” isn’t just a slogan—it’s a massive win for your protein goals, with a Half Pound Roast Beef delivering an incredible 47g of protein for just 650 calories. Yet, that nutritional high comes with a hidden cost; a single Double Roast Beef Deluxe can pack 2,150 mg of sodium, essentially hitting your entire daily salt limit in one sitting.
The real challenge at Arby’s isn’t the protein, but navigating the massive sodium spikes hidden in the sauces and sides. By using our Arby’s Nutrition Calculator to swap your sides and manage your portions, you can keep the muscle-building protein you crave while cutting hundreds of milligrams of salt, finally making your fast-food order work for you instead of against you.
The short version
- The protein is the point. Half Pound Roast Beef: 650 cal, 47g protein.
- The sodium is the problem. Double Roast Beef Deluxe: ~2,150 mg — 93% of your daily value.
- Crinkle fries beat curly fries. Same experience, ~70 fewer calories and ~220 mg less sodium.
- Arby’s says its sodium varies with your local water supply. That’s in their own guide.
What this calculator actually does
It totals calories, protein, carbs, fat and sodium for your full Arby’s order — the roast beef, the Beef ‘n Cheddar sauce, the curly fries you didn’t downsize, the Jamocha shake, all of it.
Arby’s publishes good data. The catch is that a meal here is an assembly: sandwich plus fries plus sauce plus drink, and each one carries meaningful sodium. Nobody stacks four numbers in their head at a drive-thru speaker.
How to use it in ten seconds
- Pick your sandwich — roast beef, Beef ‘n Cheddar, Market Fresh, chicken, gyro.
- Add your side. Curly or crinkle. This matters more than you think.
- Add sauces. Arby’s Sauce, Horsey Sauce, cheese sauce — they’re not free.
- Add your drink and shake.
Then run the test: keep your sandwich exactly as is, switch curly fries to crinkle, downsize them, and move the sauce to the side. Watch the sodium fall by hundreds of milligrams while your sandwich stays untouched.
The protein is genuinely good
Let’s give Arby’s its due, because this is where it beats most of fast food.
| Sandwich | Calories | Protein | Sodium |
|---|---|---|---|
| Half Pound Roast Beef | ~650 | ~47g | ~1,740 mg |
| Double Roast Beef | ~560 | ~37g | ~1,390 mg |
| Classic Roast Beef | ~530 | ~27g | ~1,380 mg |
| Classic Roast Beef Deluxe | ~520 | ~25g | ~1,100 mg |
| Roast Turkey Farmhouse Salad | ~230 | ~23g | — |
| Market Fresh Turkey | ~320 | high | — |
23 grams of protein for 230 calories in the Roast Turkey Farmhouse Salad is a genuinely elite ratio — roughly 10g of protein per 100 calories, which is the same territory as a grilled chicken salad anywhere else.
Roast beef is sliced meat, not breaded and fried. That’s the structural advantage, and it’s why Arby’s works surprisingly well for anyone chasing protein.
Note the Classic Roast Beef Deluxe line. It has fewer calories and 280 mg less sodium than the standard Classic — because the lettuce and tomato displace some of the meat. Small thing. Free win.
Sodium is where it goes wrong
Now the other side.
- Double Roast Beef Deluxe — ~2,150 mg (about 93% of the FDA’s 2,300 mg daily value)
- Half Pound Roast Beef — ~1,740 mg
- Classic Roast Beef — ~1,380 mg
- Arby-Q Sandwich — ~1,250 mg (plus 23g of sugar)
The American Heart Association’s ideal daily target is 1,500 mg. So a single Classic Roast Beef — the base sandwich, the entry point, the small one — already sits close to it. Add fries and a sauce and you’re past a full day.
Cured, seasoned, sliced roast beef is a salt-cured product. That’s the trade for the flavor and the protein.
What actually helps:
- Sauce on the side. Skip the Beef ‘n Cheddar cheese sauce, or ask for Arby’s Sauce or Horsey Sauce on the side and use half.
- Crinkle over curly (below).
- Downsize the fries.
- Chopped Side Salad — about 70 calories and only 105 mg of sodium. The lowest-sodium item worth eating.
Crinkle fries beat curly fries. Every time.
This is the most useful, least-known thing on the Arby’s menu.
| Fries (small) | Calories | Sodium |
|---|---|---|
| Curly | ~410 | ~810 mg |
| Crinkle | ~340 | ~590 mg |
Crinkle fries are lighter than curly at every size — roughly 70 fewer calories and 220 mg less sodium for a small. Curly fries are seasoned; that seasoning is salt.
And sizing matters independently: choosing small curly instead of large saves about 240 calories and 460 mg of sodium.
Stack both — small crinkle instead of large curly — and you’ve made a substantial change to your meal without giving up fries at all.
“Loaded” versions of anything (cheese, bacon) add significant calories and sodium on top. Those are a different food.
Meals under 500 calories
They’re easy to build here, which is not true everywhere.
- Market Fresh Turkey (~320 cal) + Chopped Side Salad (~70 cal) + unsweetened tea (0 cal) = ~390 calories
- Roast Turkey Farmhouse Salad (~230 cal) on its own, with 23g protein
- Chopped Side Salad (~70 cal) + 3pc Chicken Tenders (~360 cal) = ~430 calories
- Classic Roast Beef + side salad instead of fries = under 450, per Arby’s own numbers
The pattern: the sandwich is rarely what breaks the budget. The fries and the shake are.
Keto and low-carb at Arby’s
Arby’s is one of the better low-carb stops in fast food, for one structural reason: the meat isn’t breaded.
- Order any roast beef sandwich with no bun. You’re left with sliced roast beef — protein and fat, essentially zero carbs. Add Horsey Sauce (creamy, not sweet) rather than Arby’s Sauce or BBQ, both of which carry sugar.
- Also good: Roast Turkey Farmhouse Salad, Chopped Side Salad, and any roast beef or turkey without the bun.
- Skip: curly and crinkle fries, Arby-Q (23g sugar), shakes, mozzarella sticks, and anything breaded.
Shakes are dessert, not drinks
Arby’s shakes run roughly 470–510 calories for a regular size, with 73–81 grams of sugar.
That’s a full meal’s worth of calories and around three days’ worth of the AHA’s suggested added-sugar limit for most adults, arriving through a straw.
Vanilla is the lightest (~470). Chocolate is ~510. Jamocha ~490. If you love the Jamocha — and people genuinely do — split it, or make it the meal rather than the addition.
Here’s a practical bit from Arby’s own guide. Soft drink nutrition is published for the Small cup, and Arby’s tells you to multiply from there: Kids Meal size × 0.7, Medium × 1.4, Large × 1.8. So a large isn’t “a bit more.” It’s nearly double.
Three things in Arby’s own guide worth knowing
These are published by Arby’s, and almost nobody reads them.
1. Your sodium depends on your town’s water. Arby’s states: the sodium value will vary based on the level of sodium in the local water supply. Two identical sandwiches in two states genuinely aren’t identical. It’s a small effect, but it’s honest, and it tells you the printed number is a good estimate rather than a measurement.
2. Fries are portioned by hand. Arby’s notes that Homestyle Fries are individually portioned at every restaurant. Your fries depend partly on who’s working. Same idea: the number is a target, not a guarantee.
3. Refined soy oil is exempt from allergen labeling. Federal regulation exempts highly refined oil derived from major food allergens from allergen declaration — so soy oil as an ingredient is not flagged. Arby’s says directly: consult your doctor to know whether you should avoid products containing highly refined soy oil.
Arby’s also marks items with a † to indicate they’re cooked in the same oil as other items. That’s a shared-fryer warning, spelled out.
On allergens generally: Arby’s identifies major food allergens on its items and states that it, its franchisees and employees do not assume responsibility for a particular allergy or sensitivity. There’s no certified gluten-free preparation — removing the bun helps, but shared fryers and shared surfaces make cross-contact realistic.
Frequently Asked Questions
How accurate is the Arby’s Nutrition Calculator?
It’s a close estimate. Arby’s states that nutrition calculations follow federal regulations regarding the rounding of nutritional data, and that sodium values vary with the local water supply. Homestyle Fries are individually portioned at each restaurant, and any customization — extra sauce, no bun, added cheese — changes the total. Use it as a reliable planning figure and check arbys.com for current values.
Does Arby’s publish official nutrition information?
Yes. Arby’s publishes a nutrition and allergen guide covering calories, fat, saturated and trans fat, cholesterol, sodium, carbs, fiber, sugars, protein and allergens for every item, and directs guests to arbys.com to calculate meals. Menu items marked with a dagger are cooked in shared oil.
How much protein is in an Arby’s roast beef sandwich?
The Classic Roast Beef has about 27g, the Double about 37g, and the Half Pound Roast Beef about 47g at 650 calories. The Roast Turkey Farmhouse Salad delivers roughly 23g for just 230 calories — the best protein-to-calorie ratio on the menu.
Which is healthier, curly fries or crinkle fries?
Crinkle fries, across every size. A small crinkle is about 340 calories and 590 mg of sodium, versus roughly 410 calories and 810 mg for a small curly. The curly fries’ seasoning is where much of the extra sodium lives. Downsizing from large to small curly saves around 240 calories and 460 mg on its own.
How much sodium is in an Arby’s sandwich?
More than most people expect. The Classic Roast Beef carries about 1,380 mg, the Half Pound about 1,740 mg, and the Double Roast Beef Deluxe roughly 2,150 mg — around 93% of the FDA’s 2,300 mg daily value in a single sandwich. Sauces and fries add several hundred more.
What is the lowest-calorie thing at Arby’s?
The Chopped Side Salad, at about 70 calories with only 105 mg of sodium. The Roast Turkey Farmhouse Salad (~230 cal, 23g protein) and Market Fresh Turkey (~320 cal) are the best full options. Pairing a Market Fresh Turkey with a side salad and unsweetened tea lands around 390 calories.
Can I eat keto at Arby’s?
Yes, easily. Order roast beef with no bun — the meat isn’t breaded, so it’s nearly zero carbs. Use Horsey Sauce rather than Arby’s Sauce or BBQ, both of which contain sugar. The Roast Turkey Farmhouse Salad and Chopped Side Salad work too. Skip fries, shakes and anything breaded.
How many calories are in an Arby’s shake?
Regular shakes run roughly 470 to 510 calories with 73 to 81 grams of sugar. Vanilla is lightest at about 470, Jamocha around 490, chocolate around 510. They provide calcium and some protein from the milk, but they’re dessert-scale — worth splitting.
Is Arby’s gluten-free friendly?
Not reliably. There’s no certified gluten-free preparation. Removing the bun eliminates the obvious wheat, but many items are cooked in shared oil (marked with a dagger in Arby’s guide), and shared surfaces make cross-contact likely. Arby’s states it does not assume responsibility for particular allergies or sensitivities.
Go build your order
Arby’s is better for protein than its reputation suggests and worse for sodium than almost anyone realizes. Both of those things are true, and the fixes are small.
Keep the roast beef. Switch the fries to crinkle. Downsize them. Put the sauce on the side. That’s it — you’ve kept every gram of protein and cut hundreds of milligrams of salt.
Scroll back up, build the order you actually place. Then swap the fries and look again.
